WebBoth deuterium and tritium are useful as isotopic tracers for the investigation of chemical structures and of reaction mechanisms. Generally the value of a tracer arises from the fact that, although its difference in mass or its radioactivity permits its detection, it is essentially active in the same way that the ordinary atoms of the element are.
